Well, I finally got the levamisole. However, it is labeled Levamisole Phosphate, injectable soln 13.65%. The insert states that each ml of soln. contains Leva. phosphate equivalent to 136.5 mg of Leva.HCL. Could anyone help me figure out the dosage. I have the Laidlaw information, but I m not certain about the Leva.Phosphat in LevaHCl connection. Also, do you think (and remember I'll only be using enough for a ten gallon tank) that the amount of phospate that will be used will adversely affect the production of algae? I could always keep the lights off for the day that I will use th e medication. Ive already received more help thtan I prob. deserve, but I already lost one badly infected female, I dont want to lose another. TIA Joe Anderson ______________________________________________________
